What 4L80E??
I got the harness, ECM, TCM and peddle. My question is, What year of 4L80E would be the best?
Some transmissions are listed for 133" wheel base. Then there's programming? ECM is a E38. Any help appreciated!
Thanks so Much,
Darrell

For General High Performance use, any model year Core can be made to work.
For Extreme use, where high temperatures can not be avoided; like a Trans-Brake with a TC dump...
Then there are very specific Model Years that should be favored.
There are Model Years that the Over-Drive and Overrun Section of the Transmission receive NO COOLED LUBRICATION AT ALL!!!
